NSW has again recorded no new COVID-19 cases in the community, after an infected Melbourne couple's trip through the state put regional communities on edge.
The couple made stops in Gillenbah, Dubbo, Forbes, Coonabarabran and Moree on their way to the Sunshine Coast in Queensland, where the wife tested positive.
Her husband tested positive as well after initially testing negative, and Queensland health authorities believe both were at the end of their illness.
Some 20 venues in the five towns have been identified by NSW Health as potential exposure sites.
Exposure at the sites occurred at various times on June 3, 4 and 5.
More than 350 contacts have been uncovered to date and four pop-up testing clinics have been established.
But the state is yet to record a positive case resulting from the scare, with no new local cases diagnosed from 18,525 tests on Thursday.
No community transmission was detected from almost 20,000 tests on Wednesday as well.
However NSW Health is still urging anyone who has visited the areas of concern since June 1 to be especially vigilant and come forward for testing with even the mildest of cold-like symptoms.
